AI Article Synopsis
- The research showcases the operation of a Pr:LiYF(4) laser that is pumped by InGaN laser diodes at a wavelength of 444 nm, using an acousto-optic modulator.
- The team achieved a peak laser power of 167 W with pulse energy of 4 μJ at a repetition rate of 11 kHz and a wavelength of 63 nm, featuring a pulse duration of 24 ns.
- A nonlinear crystal, lithium triborate, allowed for the generation of a 320 nm UV laser, reaching a peak power of 55 W and an impressive conversion efficiency of 69%, with a pulse width of 36 ns.
Article Abstract
We demonstrate pulse laser operation of a Pr:LiYF(4) laser pumped by InGaN laser diodes (444 nm) using an acousto-optic modulator. We obtained a maximum laser peak power of 167 W (4 μJ/pulse) with a pulse width of 24 ns at an 11 kHz repetition rate for a 63 nm wavelength. Employing an 8 mm long lithium triborate nonlinear crystal in the laser cavity, we obtained a maximum peak power of 55 W (2.7 μJ/pulse) at 320 nm, which corresponds to a conversion efficiency of 69% with respect to the fundamental laser energy. The UV laser pulse width was 36 ns.
